Resumo: We investigate some aspects of the (2 þ 1)-dimensional Gauss-Bonnet black hole proposed in Hennigar et al. [Phys. Lett. B 808, 135657 (2020); Classical Quantum Gravity 38, 03LT01 (2021)]. The perturbations of scalar and massless spinorial fields are studied suggesting the dynamical stability of the geometry. The field evolution is analyzed calculating the quasinormal modes for different parameters and exploring the influence of the coupling constant of the theory. The hydrodynamical modes are also obtained in the small coupling limit. Furthermore, the entropy bound and the dominant semiclassical correction to the black hole entropy are calculated.
